"Article 22: Authentic texts. The original of this Convention, of which the Arabic, Chinese, English, French, Russian and Spanish texts are equally authentic, shall be deposited with the Secretary-General of the United Nations."
On this page you will find the six UN authentic texts of the treaty as well as other translations. The additional translations have been done by governments and ICBL campaigns. The ICBL cannot vouch for the correctness of any of these translations (should they be used for legal disputes please also refer to the UN original languages).
